Embodiment 1

[0027] A kind of bamboo liquid wash-free gel hand sanitizer, its composition comprises by weight percentage:

[0028] Bamboo leaf extract 1.0%, ethanol 45%, carbomer U20 0.4%, glycerol 0.2%, triethanolamine 0.4%, triclosan 0.4%, and the balance is water.

[0029] Further, the described bamboo liquid extract is obtained through one extraction, two extractions and three extractions by adopting the leaves of Pachyphyllum edulis.

[0030] Further, the first extraction is to soak the bamboo leaves in boiling water for 4 minutes, then put the bamboo leaves into alcohol with a concentration of 75% and heat them for decolorization, take out the bamboo leaves and dry them, add water of equal quality and grind them into The slurry is hydrolyzed with a compound enzyme of 3% by weight of dry bamboo leaves for 3.5 hours, recovered by the compound enzyme, and filtered to obtain a filter residue and a filtrate, and the extract A is obtained after the filtrate is concentrated.

Abstract

The invention belongs to the field of disinfection and sanitation, and particularly relates to a bamboo liquid no-wash gel hand sanitizer and a preparation method thereof. Effective components extracted from lophatherum gracile in a fractional extraction mode are added into the no-wash gel hand sanitizer, so that the hand sanitizer has a broad-spectrum and efficient sterilization effect, has a good killing effect on escherichia coli, staphylococcus aureus, pseudomonas aeruginosa and candida albicans, and also has an original inhibition effect on surface antigens of clostridium and hepatitis B virus; the hand sanitizer is good in stability and free of irritation to skin; no essence, spice or food coloring is added, so that the product is endowed with original plant fragrance; and the preparation process of the hand sanitizer is relatively simple and suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of disinfection, cleaning and sanitation, and in particular relates to a bamboo liquid wash-free gel hand sanitizer and a preparation method thereof. Background technique [0002] Many of people's daily activities are completed by two hands, and there are many things in contact with, and there are various stains on them. Therefore, washing hands is the most frequent occurrence in people's daily hygiene and cleaning life. Therefore, hand washing products arise at the historic moment. Restricted by living conditions and the market, people used to wash their hands with soap, soap and washing powder. Although they can achieve a certain cleaning effect, they are irritating to the skin. Long-term use will cause some people's skin to be rough and dry. Cracking and peeling. With the advancement of technology, the application of new surfactants, additives and mild, natural disinfectants, hand sanitizers emerged as the times ...
